According to CNN the shooting erupted at 9:35 a.m. at Sandy Hook Elementary School in Newtown. “I was in the gym and I heard a loud, like seven loud booms, and the gym teachers told us to go in the corner, so we all huddled,” one student said. “And I kept hearing these booming noises. And we all … started crying.

“All the gym teachers told us to go into the office where no one could find us,” she added. “So then a police officer came in and told us to run outside. So we did and we came in the firehouse and waited for our parents.”

The gunman is beleived to have fired at least 100 rounds. Two 9mm handguns were recovered from the crime scene.
